Why induction harden?
Advantages of induction hardening gear and sprocket teeth include: 1. Localised hardening of tooth surfaces where hardness is needed. Unlike case hardening which places a hard case around the entire surface of the part being hardened, induction hardening only hardens the area near the applicator coil which means that sprockets and gears will have hard teeth and not hard bores which can prematurely wear crankshafts. 2. Hardened teeth are pre-work hardened. The process of induction hardening simulates work hardening in the engine. This means that the sprocket or gear is ready to be used without the wait of the normal work hardening period. 3. Speed of hardening. Induction hardening is a rapid process. It takes approximately 30 seconds for a rod of parts to be completed. 4. Depth of hardness is easily controlled. Since the process is computer controlled the depth of hardness is always the same and is easy to control.
